Conversation
Bump the pinned Lean toolchain from v4.31.0 to v4.32.0 and move Mathlib to its matching v4.32.0 tag. All packages (interpreter, codelib, programs, verifier) build clean with no proof or API changes required; regenerated lake manifests accordingly. Also bump doc-gen4 to its v4.32.0-compatible commit and update the README Lean badge. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

CI needs no changes: the workflows read the toolchain from
